"This was my spring check up on air conditioner before running.. Everything went very well. Everyone should have a service contract with GSM they are the best. I have tried others but they do not compare to GSM."

"I called and Mike returned my call quickly and set up a date. He came and checked the air conditioner. He did not try to convince me it needed any else other than a check up. Was quick and efficient and mannerly. I would certainly use him again even for more serious repairs.

"Amazing, helpful, and caring. We had been working with another person for our ac work. Long story short, we started getting the run around. We started searching for another contractor, lo and behold, we came across Mr. Furnace. Before he even got completely in the attic, he knew what had happened. Let’s just say, the prior contractor left us in a mess. We had no clue the carelessness and danger the other contractor had put us in. Our gas lines were just dangling, the water line was shut off, instillation was coming out, and they had stepped on ducts and they were caved in. We were told if the gas lines would have hit a copper line, we would have all been in serious danger. Before they started the job they were hired for, they corrected what they could to ensure our families safety. They were very professional, friendly, and caring. We still have work to be done to get it all back correctly and will only be working with them from now on. Pricing is exceptionally reasonable for the job."

"GREAT PEOPLE TO WORK WITH."
Most professional HVAC technicians require two to three hours to complete an expansion valve replacement. The timeframe depends on your unit's accessibility and whether additional repairs are needed. The process involves recovering refrigerant, removing the old valve, installing the new component, and recharging the system. Scheduling during less busy seasons may result in more convenient appointment times.
Operating your air conditioner with a malfunctioning expansion valve isn't advisable. Continuing to run the system could potentially damage other components, particularly your compressor, which is significantly more expensive to replace. If you notice performance issues like inconsistent cooling or unusual noises, it's best to have your system inspected before continuing regular use.
Expansion valves don't have a standard replacement schedule, as their longevity depends on system usage, maintenance frequency, and environmental factors. Regular professional maintenance helps identify potential valve issues before they cause system failure. Having your HVAC system serviced annually allows technicians to monitor component condition and recommend preventative replacements when necessary.
Refrigerant leaks require prompt professional attention. If your expansion valve is leaking, you'll likely notice reduced cooling performance and possibly hear hissing sounds near the unit. Addressing leaks quickly prevents further system inefficiency and avoids the environmental impact of released refrigerant. Your HVAC technician will need to repair the leak and recharge the system with the proper refrigerant type and amount.
Because many AC issues present similar symptoms, professional diagnosis is recommended. Problems like inadequate cooling, inconsistent temperatures, or strange noises could indicate expansion valve issues, but might also stem from refrigerant leaks, electrical problems, or airflow restrictions. A qualified HVAC technician has the tools and expertise to accurately identify the root cause and recommend appropriate repairs.
